Some devices may give an error stating that INTERACT_ACROSS_USERS_FULL
permission is neeced. This permission can only be achieved by signing the
application with the same key as the system, which is never going to happen so
deal with it by catching any exceptions setting the mode may cause and failing
as gracefully as we can.

When a dialog is opened on Android, full-screen mode is exited but we (the app)
know nothing about this. Make sure we re-enter full-screen mode once a dialog is
closed, if the conditions to be in such mode are still met.

It will render as white in dark backgrounds. This is what FaceTime does and what
we already do on Android. The problem with the default look (black text) is
noticeable in audio only mode, since the background is dark.

fix: change string displayed when previewing a muted video input

Instead of using AtlasKit Single-Select, use Dropdown. Dropdown
differs in that an icon can be specified for the trigger element,
whereas Single-Select currently supports icons for all elements,
and Dropdown can show all options incuding the already-selected
option.

This change does introduce the issue of the trigger element not
taking up 100% width of the parent. Supporting such would involve
overriding AtlasKit CSS. The compromise made here was to do a
generic override of max-width so the trigger elements at least
stay within the parent and aligning the trigger elements to the
right.

fix(config.js): remove unused 'logStats'

This config option is not used anymore.

Some atlaskit components, such as field-text, inherit text color.
This is a problem with components that are white as they will
inherit $defaultColor, which is a light gray. So instead, for
the atlaskit modal, set a color for all the form content so it
can be inherited instead.

Dialog does not currently support displaying dynamic strings
for titles, only static strings listed for translation. Accept
a new prop that explicitly states it is for setting the title
and have the web dialog prefer it over the titleKey.

When the prosody setting has muc_allowners, everyone joins as a
moderator. In this case, the local user will not be set as a
moderator in the redux store as the USER_ROLE_CHANGE event will
trigger with the local user id before the redux store has set
the actual local user id--something that happens on
CONFERENCE_JOINED. The fix is to explicitly signal the local user
role has changed to the redux store, which follows the
implementation of pre-existing web logic.

Explicitly set c2s_require_encryption to false

Device Selection re-uses the local video track for its preview.
When displaying Device Selection while video muted, the text
"muted" displays within the video preview, but some translations
may mistake this to mean audio muted. The text has been changed
to be explicit about video mute. This is a temporary solution;
at some point Device Selection should not re-use the local track
except for IE, the one browser that cannot get multiple tracks
from the same video input.

fix(conference): Change display name when ChatRoom is not created yet

Jitsi Meet doesn't seem to work with c2s_require_encryption set to true.
c2s_require_encryption is false by default. However it is possible that
in some Prosody configurations it is overriden by a global config to be
true. In that case Jitsi Meet might not work out-of-box. So let's set it
explicitly to be sure it is correct.

Fix spelling/grammar for  micConstraintFailedError and cameraConstraintFailedError

Over time features/base/util became a bucket where people seemed to dump
just about anything they couldn't think of a better place for. That's a
trend I don't like encouraging. Given that roomnameGenerator.js is
currently used in features/welcome only, I'm fine with moving it there
for the greater good.

Because timeUtil.js computes hours, minutes, and seconds out of a single
time/duration using three separate functions, I wouldn't recommend using
it, especially reusing it. That's why I'm even making the functions
private to their current use location.

I don't like the file/function name, I'm not excited about the
complexity of the logic it implements, and it's definitely a reusable
piece worthy of being called a utility.

Disable the button, till we need it, UI is fixed and it is tested that everything works from jitsi-meet, through lib-jitsi-meet and through jigasi.

fix: open device selection if it is the only available setting

Move logic to open device selection outside of SettingsMenu so
it can be called independently by either SettingsMenu or by
the settings button itself if no other settings but devices will
be displayed.

Saúl Ibarra Corretgé reported that Recording shows an error dialog
stating "There was an error connecting to your camera". Hristo Terezov
and Yana Stamcheva traced that the problem originates in
da4425b5c0
and, more specifically, is caused by a different order of execution due
to the move of the invocation of the function Recording.init.

The solution is to bring back the execution location of Recording.init.

CallStats log level 'info'

fix: set button font-size for modals

Reduces the log level for the CallStats module to 'info', because recent
changes are adding a lot of debug logs.

Atlaskit at times will have localized styling for font-size and
sometimes will not. The button component will inherit its
font-size whereas selectors have localized font-size of 14px. For
consistency, the cancel/submit buttons on the atlaskit modals
will also have 14px. The atlaskit story book examples also use
buttons with 14px font-size.

If toggle audio or video is executed too early and the local
tracks don't exist we fail to execute the operation. Now we store
the mute state and we are executing it after the tracks are
created

If toggle SS is executed too early and lib-jitsi-meet is not yet
initialized toggle SS will fail. Now we are storing the whether
SS is on or off and when lib-jitsi-meet is ready we are starting
SS if needed.

Remove toolbar button and icon style literals from the render method of
Toolbox.native.js.

Additionally, comply w/ coding style.

For images < 80 of size forder radius doesn't work properly (it looks like a
square with rounded corders), however, using a duble sized radius does the
trick. Go figure.

Also move (native) avatar style to film-strip styles, since  that's where it
applies. This is analogous to how the large-view avatar is styled.

New device selection modal

Cleanup existing logic for displaying and updating device
selection settings in the settings menu. In its place
is a button to open the device selection modal.

The Device Selection modal consists of:
- DeviceSelection, an overly smart component responsible for
  triggering stream creation and cleanup.
- DeviceSelector for selector elements.
- VideoInputPreview for displaying a video preview.
- AudioInputPreview for displaying a volume meter.
- AudioOutputPreview for a test sound output link.

Store changes include is primarily storing the list of
available devices in redux. Other app state has been left
alone for future refactoring.
